Plastics are versatile and durable, but it is precisely their long durability that is the problem: petroleum-based plastics do not decompose and pollute the environment. Bio-based alternatives made from renewable raw materials do exist. But they are not environmentally friendly per se unless they are also sustainably produced, recyclable or biodegradable. This is the approach taken by the PHABIO APP project.
"Microalgae on building facades can green the city"
Microalgae are a beacon of hope for the bioeconomy. Not only manufacturers of food and animal feed rely on them, but microalgae are also becoming increasingly important for the production of biofuel and new plastics. Linus Stegbauer now wants to establish these talented single-celled organisms in the construction sector. To this end, the Stuttgart chemist wants to develop biointelligent facade elements for buildings that are coated with a special biofilm made of microalgae.
